These techniques aim to remove impurities and obtain high-purity antimony products suitable for specific applications. Here are some commonly used refining techniques in antimony processing: 1. Pyrometallurgical Refining

Antimony

Antimony is also alloyed with tin to make pewter items such as plates, pitchers and cups, used mostly for decoration. One use of antimony, which is declining, is to make type metal for newspapers and magazines. Antimony is one of very few substances (bismuth and water are two others) which expand when it cools and freezes.

In recent years, many experimental studies dealing with antimony oxide ore have been carried out, resulting in new technical achievements. Much attention has been paid to improving the mineral processing technology of antimony …

Treatment of antimony mine drainage: challenges and opportunities with

It is found that iron oxides prepared by chemical methods present superior adsorption ability for Sb(III) and Sb(V). However, this process is more costly and iron oxide activity can be inhibited by plenty of sulfate in antimony mine drainage. In the presence of sulfate reducing bacteria, sulfate can be reduced to sulfide and form Sb 2 S 3 ...

A Review on Pyrometallurgical Extraction of Antimony from …

Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting. The performance of most of the pyro-processes is very sensitive to concentrate type and grade. Therefore, technology …

Antimony in the metallurgical industry: A review of its …

Like most other minerals, the processing of antimony can be reduced into three sub-industries; mineral processing, pyrometallurgy, and hydrometallurgy.

Process flowsheet development for selective arsenic …

ABSTRACT. A pyro-hydrometallurgical process is proposed in this study for the selective arsenic removal and the Pb and Sb recovery from lead softening slag, which incorporates NaOH roasting followed by water leaching, carbothermic reduction, and HNO 3 leaching as process steps. Lead softening slag, containing 63.9 wt% Pb, 17.7 wt% Sb, …
